MACHINE FOR ARRANGING RECTANGULAR ARTICLES IN PAIRS.

Specification of Letters Patent.

Patented A11 9, 1910.

Application filed June 1, 1909. Serial No. 499,482.

To all whom it may concern:

Be it known that I, HERMAN A. KREr'r, a citizen of the United States,residing at Chicago, county of Cook, and State of Illi nois, haveinvented a certain new, useful, and

Improved Machine for Arranging Rectangular Articles in Pairs, of whichthe following is a specification.

My invention relates to machines for arranging articles of a rectangularform in pairs preparatory to and to facilitate expeditious packingthereof.

The object of my invention is to provide a machine of the charactermentioned especially designed for use in the arrangement of bars of soapin the manner stated preparatory to the packing thereof for shipment.

A further object is to provide a machine as mentioned which will beentirely automatic in its operation and which will be strong and durableand of comparatively simple and inexpensive construction.

Other objects will appear hereinafter.

With these objects in view my invention consists in a machinecharacterized as above mentioned and in certain details of constructionand arrangement of parts all as will be hereinafter fully described andparticularly pointed out in the claims.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and inwhich,

Figure 1 is a perspective View of my device in its preferred form, Fig.2 is an enlarged detail of one of the rollers over which travels anendless belt embodied in the machine, Fig. 3 is an end elevationthereof, Fig. 4 is an enlarged detail of a cam wheel included in themachine, and Fig. 5 is a transverse section taken on the line a: an ofFig. 4.

Referring now to the drawings, 1 indicates a supporting framework in theupper end portion of which is rotatably mounted a horizontally extendingshaft 2, the same being driven by any suitable means (not shown)preferably, although not necessarily, through the medium of the pulley3.

4 indicates an endless belt traveling over rollers 5 and 5 mountedrespectively in the upper portion of the vertically extending bars 6 ofthe framel, and in the rearward end portion of horizontally extendingarms 7 rearwardly projecting from said bars of said frame. A pulley 8fixed to the shaft of the roller 5 and a belt 9 traveling over saidpulley and a pulley 1O fixed to the shaft 2 effects an operative ordriving connection between the latter and the belt 4. However, I do notwish to limit myself to the precise driving connection shown inasmuch asa chain and sprocket or other suitable connection might be incorporatedif desired. In order to insure a positive and certain driving of thebelt 4: by the rollers 5 and 5, I preferably provide at either of theextremities of each of the latter, sprocket- Wheels 11, traveling over,and extending between, which are chains 12 to which are suitably securedthe longitudinal edges ofsaid belt.

Such connection, it is evident, effects the purpose above stated.

Suitably secured, preferably to the upper cross bar of the frame 1, is aplate 13, the same being so arranged that the vertically disposed lowerend portion thereof is positioned directly over the roller 5 and midwaythe extremities thereof. Reciprocally mounted in the upper endportion'of the frame 1, preferably in slotted lugs 14 depending from theupper cross bar of'said frame, is a horizontally extending rod 15.Carried by said rod is a blade 16 so positioned thereon as to bereciprocated transversely of the horizontal central line of the belt atequally distant either side thereof, the entire extent of such vibrationof said plate being slightly greater than the length of the plate 13. Inorder to effect intermittent reciprocation of the rod 15, a verticallyextending arm 17 rockingly mounted upon the outer extremity of asupporting member 18 secured to and laterally projecting from the frame1, is'provided. The upper extremity of said arm being in pivotalconnection with the outer extremity of the rod 15,-the lower extremitythereof engaging the irregular groove 19 in a cam wheel 20 carried bythe shaft 2, the stated reciprocation of the rod 15 is evidentlyeffected.

Extending in vertical alinement with the belt 4, the rearward extremitythereof being preferably secured to the lower end portion of the frame1, is a guide receptacle 21 rectangular in cross section, and formedpreferably of metallic strips 21 supported at intervals by rectangularframes 23. Having its upper extremity communicating with the forwardextremity of the belt 1 and its lower extremity with the guidereceptacle 21 is an inclined chute 24-ofa width at its 1 upper extremitythe same as that of said belt and at its lower extremity equal to thatof said receptacle. Flanges 25 are provided at the longitudinal edges ofsaid chute and a similar flange 26 is provided midway said flanges25which divides the upper surface of the chute into two independentpassages 27 of equal widths. v

Having its lateral edges slidably mounted in channels 28 suitablysecured in the receptacle 21 is a preferably rectangular member 29. Aconnecting rod 30 having-its forward extremity pivotally secured to themember 29 and its rearward extremity suitably connected to a crank 31formed in the shaft 2, is evidently adapted upon the rotation of thelatter to impart reciprocatory motion to said member 29. The latter isso mounted in the receptacle 21 that, whenin a position at the rearwardlimit of its movement, as shown in Fig. 1, the forward edge thereof willbe disposed in a vertical plane rearward of that including the forwardedge of the chute 2 1, for reasons which will be obvious from thefollowing.

In operation, the device is preferably arranged with the rearward orouter extremity of belt 4: positioned adjacent a vmachine which depositsrectangular bars of for instance soap, in longitudinalalinementcentrally u on said belt. Such bars are carried forwar plate 13, thelatter actin' as a stop therefor. Upon reaching suc' position successivebars, because of the blade 16, are alter- I nately forced to the rightand left and thence carried by the belt 4; and delivered into thepassages 27 of the chute 24-. The; same descend said chute and aredirected for deposition into the receptacle 21 7 directly forward of themember 29. Thereciprocation of the member 29 is so timed that, upon apair of bars being deposited side by side in the guide receptacle, saidmember will travel forward'forcing said bars forwardly in the receptacleto such an extent as to permit of the deposition of 'a succeeding pairof bars therein upon thereturnmovement' of said member. Thus itwillbeseen that, by

"the-provision of the mechanism described,

'the preferable form of my'machine I do not "wish to' be limited theretoas there might be many changesmade in the'details of con- "structi'onandarrangement of parts without departing from the spirit of the invention;

comprehended within the scope. of :the appended'claims. And although Ihave deby said belt until they abut the signed my device with specialreference to its use in connection-with the packing of soap I may usethe same in the similar arrangement of any other articles to which it isapplicable.

Having described my invention what I clalm as new and desire to secureby Letters I atent is:

1. In a machine of the class described, the combination of a chute, aguide'receptacle in communication with the lower extremity of saidchute,means for conveying and delivering objects to said chute, meanscooperative with said chute and said conveying means for causing theobjects carried by said con veying means to be deposited in p airsintosaid receptacle, and means for forcing forwardly in said receptacle eachpair of objects deposited therein, substantially as described. V
